Collisions with electrons from several sources are common throughout planetary atmospheres. While in most circumstances direct electron impact is less significant than solar radiation, electron collisions have a major influence on the chemistry driven by both photon and particle impact. This review addresses electron collisions in atmospheres, with emphasis on cases where electron impact drives, enhances, or otherwise interacts with chemical processes. Understanding of atmospheric processes typically involves computational simulation based on theory, remotely-sensed atmospheric data, atomic and molecular physics data and chemical reaction rates. These and the modelling techniques will therefore also be covered. An example of current and future work on electron impact on the hydroxyl radical (OH) is presented, where applications in both atmospheric studies and plasma medicine are important.

大气中的电子碰撞

与来自多个来源的电子发生碰撞在整个行星大气中都很常见。虽然在大多数情况下，直接电子撞击不如太阳辐射重要，但电子碰撞对由光子和粒子撞击驱动的化学产生重大影响。这篇综述讨论了大气中的电子碰撞，重点是电子碰撞驱动、增强或以其他方式与化学过程相互作用的情况。对大气过程的理解通常涉及基于理论的计算模拟、遥感大气数据、原子和分子物理数据以及化学反应速率。因此也将涵盖这些以及建模技术。介绍了电子对羟基自由基 (OH) 影响的当前和未来工作的一个例子，
